But in JavaScript, all functions are naturally closures. In some languages, it is not possible, or a function should be written in a special way to make it happen. You can create a function dynamically, copy to another variable or pass as an argument to another function and call from a totally different place later.Ī closure is a function that remembers its outer variables and can access them. JavaScript is a function-oriented language. In the above example, the recursive function simplifies the task and calls itself. A partial case of this is when a function calls itself. In the process of solving a task, a function can call many other functions. Or when a task can be simplified into an easy action and a simpler variant of the same task.
Recursion is a programming pattern that helps in situations where a task can be naturally split into several tasks of the same kind, but simpler.
Some of the advanced working with functions include: In this advanced JavaScript Tutorial, we will get into the depth of advanced aspects of JavaScript.Ī function is a block of organized, reusable code that is used to perform single, related action. Some of the Basics and Fundamentals discussed in the previous JavaScript Tutorial are: You can run JavaScript not only in the browser but also on the server and any device which has a JavaScript Engine. JavaScript is an object-based programming language that supports polymorphism, encapsulation, and inheritance as well. Initially, It was named Mocha, then changed to LiveScript and finally it was named JavaScript. It is a Scripting Language and has nothing to do with Java. If you want your web page to look alive and do a lot more than just gawk at you, JavaScript is a must. It is a programming language that helps you to implement a complex and beautiful design on web pages.
It is a very powerful client-side scripting language that makes your webpage more lively and interactive. JavaScript is a high level, interpreted, programming language used to make web pages more interactive. In this Advanced JavaScript Tutorial, we will learn about some of the advanced aspects of the programming language in the following sequence: In our previous JavaScript Tutorial, we discussed all the basics and fundamentals of the language. It has become one of the most important languages in today’s world. The rise of the web has taken JavaScript places it was never conceived to be.
